Answer:
Step-by-step explanation:
10x+10y=-10
9x+10y=18
= 10x+10y=-10
-9x-10y=18
= x=8
step two is to find y:
10x+10y=-10
10(8)+10y=-10
80+10y=-10
10y=-90
y=-9
your answer:
(x,y)= (8,-9)
The answer of 9 3/4 as a percent is
9 (900%) plus 3/4 (75%) which equals 975%
Answer:
your mo- (3x^5 + 8x^3) - (7x^2 - 6x^3) = 3x^5 + 8x^3 - 7x^2 + 6x^3 = 3x^5 + 14x^3 - 7x^2
Step-by-step explanation:
Do elimination
2x + y = 3
x - y = 3
Add these
3x = 6
X = 2
Plug in 2 for x
4(2) + 2y = 6
8 + 2y = 6
2y = -2
X = 2, y = -1
